Macbook pro laptop non working

Please read the description. A1278 (Mid 2012) MacBook pro Machine is not working-3 beeps on startup (google says RAM issue). I'm not technology smart so I'm not ready to try fix it. Everything else was working perfectly up until this happened a couple of days ago. Only the hard drive is removed for data recovery, Everything else is included as per the picture. Comes with the charger, battery was working fine as well. Sold as is/voetstoots. If the advert is up, it is available Collection in the Hilton Business Park on appointment only
